95 z28 convertible was running fine. Went to start it one day and nothing...didnt hear fuel pump so I figured it was bad. Replaced FP and still nothing, thought maybe it was the relay. Replaced relay, nothing. Checked power at the relay with ignition switch on and no reading, needless to say no power at fuel pump either. All fuses have been checked and I am at the end of my rope. Any help would be great. Thanks.

 

Here's the schematic ref shoebox.. http://shbox.com/1/1995_pcm3.jpg If your relay does not have +12v at pin B30 w/ignition on then its the fuse, bad ignition switch, or wiring. Try jumping +12v to the prime connector and make sure pump runs. That bypasses fuse, wiring, and the relay ref shoebox again http://shbox.com/1/fuel_pump_prime.jpg
